Answer:
Coordinates of other end point L = ( -19, 13 )
Explanation:
The mid point of the coordinates (a,b) and (c,d) is given by 
Here we have (a,b) = (1,-7) and
= (-9,3) , we need to find (c,d).

So coordinates of other end point L = ( -19, 13 )
<h2>
Weight of column is 555.83 N</h2>
Step-by-step explanation:
Size of column = 6 inch x 6 inch x 8 ft
Size of column = 0.5 ft x 0.5 ft x 8 ft
Volume of column = 0.5 x 0.5 x 8 = 2 ft³
Specific weight of concrete = 62.4 lb/ft³
Mass = Volume x Specific weight
Mass = 2 x 62.4
Mass = 124.8 lb = 124.8 x 0.454 = 56.66 kg
Weight = 56.66 x 9.81 = 555.83 N
Weight of column is 555.83 N
